SAMUEL J'. SCOTT, 0F COLUMBUS, OHIO, ASSIGNOR OF ONE-THIRD T0 JAMES O. SLOAN AND ONE-TIIIR-D T0 ISAAC N. GATRELL, BOTHl MOVING ADVERTISING DEVICE.

To all whom t may concern:

Be it known that I, .SAMUEL J. SCOTT, citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Moving Advertising Devices, of which the following is a specification.y

My invention relates to the improvement of moving signs and the objects of my invention are, to provide an improved mechanism by means of which advertising cards or signs may be successively displayed through the traveling movement ofa continuous support; to provide improved means for insuring a uniform operation of the traveling support; to provide means for reducing the-friction of the parts; to produce improved means for attaching the sign cards to the support or carrying device and to provide other improvement. Ithe details of 'which will be more fully pointed ,out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawing, in which- Figure 1 is a perspective view of my improved sig'n cases. Fig. 2 is a vertical lon` gitudinal section of the same, showing part of the internal mechanism in ele vation. Fig. 3 is an enlarged vertical section on line .fr a: of Fig. 2. Fig. l is an enlarged sectional view illustrating amotor drive hereinafterdescribed. Fig. 5 is a face view of a portion of one of the sign cards. Fig. 6 is a view in elevation of a portion of one of the sign cards retaining bars or cleats, and Fig. 7 is a front elevation of a portion of a chain belt which I employ in the manner liereinafter described.

Similar numerals refer to `similail parts throughout the several views.

In carrying out my invention I employ an elongated casing or housing-,such as is indicated at 1, said housingbeing of a suitable length and being provided in its forward side or face, throughout the greater portion of itslength, with an opening 2. One end of the casing is, as indicated vat 1, slightly enlarged and in said enlargement is mounted a suitable motor 3, the shaft 3 0f which has a gear connection with a worm Wheel 4, said worin wheel being carried on a.

vertical shaft 5, which is mounted in the outturned arms of a bracket 6, the latter being. supported from a vertical frame member 7,

which is within the enlarged portion of the housing 1. The shaft 5 extends through the upper side of the housing 1 and carries a small sprocket wheell 5a.

Mounted vertically in the casing 1, adja! cent to the enlargement 1, and near ythe opposite end ofsaid casing are vertical shafts Sand 9. Each of these shafts carries a vertical sleeve or roller. shown at 10 and 11, each having a .reduced central portion l0a and 11a. And each of these roller bodies is preferably formed of two sections 0f equal length and between the reduced adjacent ends of these sections ismouuted upon the central shaft a sprocket wheel 12. As shown in the drawing, the upper and lower ends of the rollers 10 and 11 are ata distance from the upper and lower sides of the casing l and each of said roller ends has affixed thereto an end plate. such as is more clearly shown at 13 infFig. of the drawing. On the outer side o t' each ot the end plates the central shaft H or surrounded by a set or plurality of vertical roller bearings 14, each set. of which vis incased movably Within a belt wheel 15. Each of these belt wheels 15 is formed with a disk-like bottom plate 15, and between said bottom plate and the adjacent plate 13 are provided bearing balls 15". Running over theupper belt wheel 15 is a belt 16 and ruiming over the lower belt Wheel 15 is a belt 17. 18 represents a chain belt which Aruns over the sprocket wheels 12 of the rollers9 and 10. At desirable.` intervals, the upper and lower belts 1G and 17 are connected by vertical cleats or strips 19,- the end portions of said cleats being preferably riveted to said belt. 'Each of these cleats has projecting Voutwardly therefrom, at intervals, pins 20, the outer vend portion of each of said pins having a threaded socket to receive 'the threaded stem of an enlarged pin head 21 (see Fig. 8). The chain belt 18 is at one or more points connected with one of the cleats 19 through the medium of a pair of short connecting chains 22.

23 representseparately formed advertis ing cards, each card having formed therein adjacent to each end slotted openings 24, these end openings being adapted to receive the outwardly projecting pins 20 of the cleats19 and'the ends of the cards attached y thus being made to over-lap each other. The upper portion of each -of the cards 23 1s further connected with the upper belt 16 by the engagement of a button 25 which projects from said belt with a horizontal slotted opening 26 formed in the card.

27 represents outer side vertical cleatsor retaining bars which are provided wit-hopenings to receive the outer end portions o the pins 20, said cleats being held on said pins by the pin heads 21. The lower end of each' of the cleats 27 has formed therewith downwardly projecting fingers 27, in which is mounted a bearing balll 27h, said bearing'balls being adapted to run upon the casingl and the lower side of the opening -2, and thus form-an anti-frictional support op the connected signs and their carrying e ts.

The ends of the vertical shafts 9 are preferably mounted in blocks 28, which are slidably mounted in elongated recesses 29 formed in the upper and lower sides of the casingil F rom each of these bearing blocks extends outward through the end of the casing a rod or stem 30, havlng an enlar ed head, and bey tween said head and the en of the casing is`v provided a coil spring 81, the tension of i which serves to hold the bearings 28 in such A positions as to retainthe vbelts in taut condition. f

Upon the upper end of the shaft 8, above the vcasing 1, is carried a sprocket wheel 32, which is connected with the sprocket wheel 5a through the medium of a suitable belt 33.

In operation it Will be understood that a rotary motion is imparted from the motor shaft Y3a through the .worm wheel 1 to the shaft 5, and that .through the belt connection of,` the sprocket 4wheel 5a and Wheel 32 rotary motion is contributed to the shaft 8 and its roller 10. Through the chain belt -connection of the rollers 10 and 11` a rotary motion is'imparted fronr one of said rollers to the other and through the medium of the connecting chains 22 a connection between the chain belt 18 and the belts 16 and 17 is provided, which insures a traveling motion of said belts about the wheels 15. It willthus be understood that the sign cards successively arranged upon the traveling carrying mechanismwill move successively past the opening tube of the casing l.

It is obvious that a sign displayin device of. the character described maybe e eotively utilized in public places. v

While the elements shown and described Wheels, a pair of vertical rollers mounted being located. upon each side of the correspending sprocket Wheel, a ball race containsaid rollers, a belt pulle mounted upon the 'upper and lower end o each of the shafts, vertical roller bearings between said belt pulleys-and theshafts, ball race containing plates carried by the inner side of said belt pulleys, balls disposed in said ball races, belts passing around said belt pulleys, and display card supporting members connecting said belts and attached to said chain belt.
